ABSTRACT
The interaction between carbon nanotubes and organic molecules including benzene (C[sub 6]H[sub 6]), cyclohexane (C[sub 6]H[sub 12]), and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ: C[sub 8]N[sub 2]O[sub 2]Cl[sub 2]) have been studied using first principles calculations. The equilibrium tube-molecule distance, adsorption energy, and charge transfer are obtained. The hybridization between the DDQ molecular level and nanotube valence bands transforms the semiconducting tube into a metallic one. Coupling of π electrons between tubes and aromatic molecules are observed. Our results show that noncovalent functionalization of carbon nanotubes by aromatic molecules is an efficient way to control the electronic properties of carbon nanotubes.
